I was out of my car and it started raining that with flood and now I got water in my oil could it be From oil pan


No the oil pan is sealed,unless you had a major hole. But you would have also had a oil leak.Water in oil is a sign of either a intake gasket or head gasket leak.

How to back flush heater core 2007 grand prix


drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.

Flushing the coolant system


Once the engine has cooled, locate the radiator drain plug and place a large catch pan underneath it. To expedite the draining process, remove your radiator fill cap to allow air to enter the system. With the cooling system refilled with tap water, replace the radiator fill cap and run the engine allowing it to reach operating temperature.drain radiator,
At this point, if you have opted to purchase a radiator flush kit, you should refill the cooling system with tap water and add the caustic fluid as directed.
Run the engine for as long as the radiator flush kit calls for (usually less than 10 minutes). follow directions on bottle for flushing. if you feel you want to use a T connection just cut into return line, from heater core. then you can use a garden hose to flush system.

How do I flush the cooling system in a 2000 hyundai elantra?


There are several methods for flushing the cooling system on ALL engine cooling systems. Time honored is drain the radiator (drain ****). Fill with fresh water and run engine to operating temperature until cooling fans turn on. Drain cooling system again. Refill with 50-50 coolant. Another method is purchasing a "T" vlave (coolant flush/service kit) from Autozone, PepBoys, NAPA, O'Reilys, CarQuest, etc.). This "T" valve is installed in one of the heater hoses & attached to a garden hose. Remove the radiator cap & turn on the water supply to the garden hose. Let water run until flush water is 'clear'. Remove garden hose from T valve & refill radiator with pure coolant until the T valve drainage turns green/orange. Install T valve cap... DONE!

1990 toyota pickup is running hot and when i shut


Try with the small stuff first. Replace the thermostat. Before you do that, you should flush and refill your system with just water after the flush process. The bottle of solution that you put into your radiator to flush it and clean it has instructions, follow those. Then let the car cool down and drain the system and refill it with fresh water only. Run this water for a bit and then do it once more. Once cooled back down , replace thermostat and replace the 50/50 mix of antifreeze and water.
Check engine oil level as well, low oil will overheat engines quickly.

How to change/flush coolant on a 2003 jetta


Slap on those vinyl gloves because the ethylene glycol in antifreeze can cause skin damage - however we recommend this because the antifreeze feels like engine oil.With your catch pan in place, remove the radiator drain plug and collect all old coolant. Immediately dispose of the coolant as required by environmental laws - if you are to surrender the old coolant at a waste management facility, be sure you use containers which can be properly sealed to avoid spillage, etc.To expedite the draining process, remove your radiator fill cap to allow air to enter the system.
Also be sure to remove all coolant from your radiator reservoir. We suggest you use the gravity siphon trick - just be sure not to ingest any coolant.

Watch the old coolant as it exits the system - this will give you a good idea of your vehicle's cooling system condition.If you see metal flakes, oily surface, white flakes, etc .. you can make a diagnosis of your engine's coolant system.
Essentially, if you see anything but coolant and some very minor debris, it can indicate the early signs of cooling system failure.When all coolant has been drained from the radiator, replace the radiator drain plug and then fill the system with plain tap water to dilute remaining antifreeze in the engine block.
With the cooling system refilled with tap water, replace the radiator fill cap and run the engine allowing it to reach operating temperature.When the engine's cooling fan turns on, it is an indication that the vehicle's thermostat has opened, allowing the freshly added water to circulate through the engine thus diluting the remaining coolant. Allow the engine to run for a few minutes before shutting it off.
At this point, you can either wait until the engine cools off, or take fate in your own hands and continue the flushing process.Repeat the draining process being sure to once again collect and dispose of all waste coolant.
At this point, if you have opted to purchase a radiator flush kit, you should refill the cooling system with tap water and add the caustic fluid as directed.
Run the engine for as long as the radiator flush kit calls for (usually less than 10 minutes).

Once again, drain the cooling system, collecting all waste fluid. This is the last time you will be required to collect engine coolant during this process.Now that the cooling system is empty, replace the radiator drain plug and refill the cooling system with distilled water only. The reason that you should only use distilled water at this point is to avoid mineral deposits which will deteriorate your cooling system over time.
Once the cooling system has been completely filled, start the engine to allow the water to circulate. Once again remove the radiator drain plug. As the engine runs, pour fresh distilled water into the radiator fill hole at the same rate that it exits the system.Continue this process until the water being drained from the radiator appears to be clear and free of debris. Once you are satisfied with the drain water's appearance, stop the engine and allow all remaining water to drain out.Replace the radiator drain plug and prepare to mix your distilled water and coolant.
Be sure to mix your coolant to the ratio recommended by your manufacturer. In most cases, the ratio is 50% distilled water and 50% coolant.
As a tip, mix the coolant and water in a third container being sure to observe the proper ratio.As you mix your water and coolant, use your hydrometer to measure the specific gravity - this will give you a good idea of whether or not you are mixing the coolant and water properly.
Once you have mixed enough coolant and water to fill your engine's coolant system entirely, grab a funnel and place it in the radiator fill hole.Fill your radiator at a rate of no more than:
{ 1 L/min. \ 1.1 US qt./min. \ 0.9 Imp. qt./min. }.
Continue the filling process until the coolant reaches the bottom of the fill neck. Now fill the radiator reservoir to the full mark.
With the radiator fill cap still off, start the car and allow it to idle. As the engine runs, continue to add coolant as air escapes the engine and cooling system.As you top up the radiator, be sure to "burp" the cooling system by firmly squeezing the radiator hoses (both upper and lower). Continue to squeeze and release the hoses to help push any errant air bubbles out of the system.
Once you are unable to fill the radiator any further, replace the radiator fill cap and stop the engine - you are finished.
